“I say potato, you say potahto”: Geographic variation in contact calls of Canadian beluga whales
Many species of birds and mammals exhibit intraspecific acoustic geographic variation in their vocalizations. This occurs when populations are separated by some distance and do not have a chance to interact. A recent study, published in Marine Mammal Science, investigated geographic variation in the well-studied contact calls of beluga whales, a socially complex species known for its rich vocal…
